The invention relates' to a new and im'- proved machine designedprimarily for washing and cooking food, although certain features arenot restricted to this particular field. One of the notably shrimp, andit is one aim to provide a novel and advantageous machine for firstWashing the shrimp', for then cooking and blanchingthe same, and forfinally discharg- Y ing the washed, cooked and blanched shrimp upon aconveyor or into a receiver, as maybe tents of the receptacles separatedand consequently insuring better results than if'such contents Werecarried through the cooking tank'in bunched formation.'

A still further objectof the invention is to provide novel means yfordumping the reof the machine.

Yet another aim is to provide a unique rel ceiving chute intowhich the'receptacles arel ject matter hereinafter y claimed, description beingaccomplishedbydumped and to make` unique provision for alternatelymovingsaidchu'te into and out of receiving position.

A further object is the provision of a ma' chine which, While being ofrather simple.

construction will be eflicient'and desirable from all standpoints. y

With the foregoing andminor objects in view, theinvention resides in thenovel subdescribed vand reference to the accompanying drawings, `rFigs..1 and 1a tudinal sectional view partly in elevation,y through amachine constructed in accordance with our invention.

However, even though this construction -Will be ratherspecicallydescribed for illustra- .tive purposes, it is to be ,understood thatWith in the scope ofthe invention asclaimed, nu-V n mei-ous. variationsmay b e ,made i. i I The numerals 5, 6, 7- and 8 denote a plurali-` 7j'ty .offpairs of vertical standardsl Secured-ite and risingffiom sills9, there beinganysuitable number of these standards, 'according to` thelengthof theV machine. The upper ends of the standard-Sare connected bytrans-` 80 cept-acles when they reach the delivery verse plates'or thelike 10, 1andsecured upon f f1 Y number of longitudinal bars i l1.Approp-riately mounted upon these barsV 1 11 at one end-jef the machine,Wehave illustrated anV electric motor 12for driving the 85 entire:machine as will be hereinafteraieXifl plaiiied.` Secured upon thetwoplatesl lO'at* the opposite end of the machine, are tvvo an f glemetalibars 13 which project beyond'the standards 8 4andcarry appropriatebearings 90 Q14 in which a transverse shaft 15 is rockably,l i

mountedth e chute -16 above mentioned, being'y A secured to said shaftl.The shaft: is operated in a manner l hereinafter explained, to controlthe movement of the chutelG to and 96 at Which itreceives the. ycontents of the load-carrying receptacles.

Rigidly mounted' between the pairs-fof ,Y standards 5 8, are a loverhorizontally ,elong gated vvashingr tank 17 and an upper smi- 100 larlyelongated cookin tank 18. Two opposed, parallel, longitu inal tracks 19are secured to the standards 6-4-7'7a11d any which may intervene, at theupper longitudinal -edges of the cooking tank 18. -Two similar tracks 20are secured .to all of the standards -8 at the upper. edges of thewashing tank V'17. These tracks and certain rollers 'co-op-`erable-therewith 'takethe real weight of the load carriedthrough themachine, from-endf less chains which move said load.

Mounted yupon a shaft 21 su ported in appropriate bearings` by the stanards 5, are

two large sprocket wheels 22. Similarly carried by av ,Shaft 23supported by the standards 8, are two large su rocket wheels 24, the twoshafts 21` and r23 disposed at the upper edges ofthe end wa ls of thecooking tank 1,8. VVTwo/endless chains 25 are tra-ined aroundY thesprocket vwheels 22 and 24, .said

chains having bearings 2 6 at spaced points in which transverse shafts27 are rotatably mounted. Secured to these shafts are the receptacles28, said receptacles being preferably in the form of wire baskets. It isin these baskets that the commodity is carried firstA through the washintank 17 and then through the cooking; tan Y 18. Theends of the shafts 27are provided with rollers 29 which travel u on theJv tracks 19.?20 sothat the weight of t e basket contents is relieved from the upper andlower reachesof the chains 25. The two reaches of these chains arepreferably spaced downwardly from the upper and lower edges ofthe/sprockets 22 and 24, and appropriate idle Sprockets `30 are providedon the. standards 5` and 8 to guide said reaches at the ends ofthetracks 19.20. j

j Secured tothe, shafts 27', at one end thereof, are toothed wheels 31.These wheels are successively co-,operable with a curved track jori-'ack har 32 approl riat'ely mounteduponk a curved bar 33 whicr` islsuitably secured toi the frame ofthe machine. The rackA bar 32 is in thepath of the wheels 31 and each time Yone of these-wheelsl engxges saidrack bar, Y as shown for instance 1n of this wheelisfrotated, causing itto invert' the basket 28. as showny in this view. At the time thisoperationtakes place, the chute 16 Y occupies the receiving positionshown in this same f1 re, so that the basket contents slide Vdown t echute and off into a receiver or to a.

conveyor, as desired. The position of the chute 16. is controlled-by therollers 29 at one side of the machine, as will hereinafter appear.

i We have above stated that the chute 16 is secured to the shaftl. Alsosecured to this shaft, are a gear 34and al weighted arm 35. The gear 3.4is in constant mesh with an arcuate rack; 36 which is pivotally mountedat 37 upon one of the barsl 13. This rack 36 is provided with a.depending actuating arm 38 which is cooperable with the rollers 29 .at

ig. 2the shaft 2,7

one side of the machine, as will be clear from Figs. 2 and 3. Whenever aroller29 engages the arm 38, it causes swinging of the rack 36 about thepivot 37 and said rack drives the gear 34 to rotate the shaft15,-thereby outwardly swinging the chute 16 to the position shown inFigs. 1f* and 3. As soon as the roller 29Velear's the actuating arm 38however, the chute 16 swings downwardly and inwardly by gravity to theposition illustrated in Fig.

. 2 and bythe time it reaches this position, a

basket 28 is inverted to discharge its contents onto said chute. Theweighted arm 35 merely counterbalances the weight of the chute 16 tosome extent so that it will be less diiicult to swing this chuteoutwardly to the position illust-rated inFigs. 1 and 3. v Y

Extending longitudinally above the bottom of the washing tank 17, is apipe 39 having perforations 40 at intervals, said pipeV extending from ablower or the like 41. Air jets are upwardly discharged from theperforations 40 through the Water in the washing'tank 17, las indicatedby the vertical arrows in Figs. 1- and 1". These air jets agitate thewater and when shrimp or the like are being carried longitudinally inthe tank 17, said jets cause them to lash about vigorously in thebaskets 28 so that they will thoroughly wash themselves.

plurality of steam pipes 42 are disposed longitudinally over the bottomof the-cooking' tank 18, each of said pipes having a return bend 43(Fig. 1). One end of each pipe communicates by appropriate piping 44with `a steam supply manifold 45 as seen in Figs.

1 and 4. The other end of each pipe is provided with a steam dischargedevice such as a trap 46. Steam from the lpiping 44 in passing throughany steam pipe 42 and returning to theV trap or the-like 46, highlyheats oneV reach of the pipe but does not so highly heat the returnreach thereof. Hence, with each ypipe provided with a comparatively hotVand a relatively coolV reach, a number of circulating zones of waterwill be set upv in the tank 18. This circulating water is of the-likefrom `said chute 47 into the basketsA 28 as the latter slowly arrive atpositions beneath the inner end of said chute. The baskets 28 conveytheir contents longitudinally within the washing tank 17 as indicated bythe arrows on a number of said baskets inthe 'lower portions of Figs. 1and la. At the end Ih i .mounted at the ends of the chains 25 andsprockets 21 elevate them'fromthe tank 18. The wheels 3l cofactWitligthe rack 32 in successively inverting the baskets 28 to adischarge positionas` will be clear from Fig. 2, and the rollers 29 andarm 38 co-operate in effecting movementof the chute 16 to or fromreceiving position. lVhen this chute is in the position shown in Fig. 2,it receives the contents of the basket being dumped and such contentswill slide down the chute into a receiver or onto a conveyor, asdesired. By the time this has taken place, the roller 29 of the basketwhich has just discharged, strikes the arm 38, swings the latteroutwardly as disclosed in Fig, and hence the dumped basket is allowed topass to again descend into the washing tank 17 The sprockets 22 or thesprockets 24 may be driven, as may be desired. In the present showing,the shaft `21 of the sprockets 22 is provided with a worm gear meshingwith a Worm 51 on a short longitudinal shaft 52 which is appropriatelymounted (see Figs. l and 4). Shaft 52 is`provided with a spur gear 53meshing with a pinion 54 on another short longitudinal shaft 55 whichisrlriven by a chain 56 and appropriate sprockets from the motor 12.
